Hello! I'm Rohit Shakya, a Senior Backend Engineer with over 5 years of experience building cloud-native, low-latency, distributed systems using Java, Kotlin, and Spring Boot.
I’ve worked across EdTech, E-commerce, Healthcare, and Classifieds domains—contributing to end-to-end backend development, system design, and performance optimization. My experience includes API development, payments integration, RBAC systems, logistics workflows, database/query optimization, and building reliable healthcare data pipelines.
Currently, I'm working at OLX Indonesia in a large distributed microservices ecosystem (150+ services). My work includes designing new services, improving performance & latency, integrating moderation/monetization flows, building event-driven systems with Kafka/SQS, and contributing to observability, refactoring, and on-call operations.
